Came across a few posts that recommends APC with Total Cache plugin for WordPress. But, I was told by hostgator "Our default cPanel installation uses suPHP with the "event" MPM...please be advised that suPHP is not compatible with the APC opcode cache. ".
And, they also said, "we could try switching php to DSO instead of suphp. The advantage of suphp is better security. Moving to DSO would require that permissions on files be updated and some files would require 777 or 666 permissions in order for them to work properly."
I have very little knowledge about server or coding; need some advice on (1) whether hostgator's recommendation is good for installing APC on hostgator VPS server (2) if it is, after switching to DSO, can file permission update be easily done, and bad consequences for wordpress sites?
Thanks a lot for your time and help.
